To my conclusion, I believe I am right about the fact that 9+10=21. That fact is well known to society. There is even a viral video explaining this. https://www.youtube.com...
This is definitely a reliable source because the kid even admits that he is not stupid! it is obvious that the media today has accepted this fact. 9+10=21 it's simple. I mean if the internet says it, it is OBVIOUSLY correct. I don't know where this "19" lie came from, and that is why you should vote for me. Everyone knows that 9+10=21 and anyone who disagrees with that not only thinking against what society thinks, but they are saying that the kid in the video is wrong! That is very mean to the kid in my opinion!
Thank you for reading!

C1: 9+10=19 because that is mean to the kid. My opponent even admitted this in his argument. Being mean to kids is commonly accepted as beneficial. Just look at how many parents physically punish their kids.

C2: Addition is defined as putting the first digit of the second number onto the first number[1]. My opponent did not give a definition of addition in his round, so my definition wins by default. The first digit of 10 is 1, so we put that in front of 9 to make 19.

C3:

P1: If an almighty being says something, it is true
P2: I am an almighty being
P3: I say 9+10=19
C: 9+10=19

This syllogism is logically valid[2], and all the Premises are true. My opponent must prove me wrong as he has BOP.
